KNOB AND HANDLE FOR STOVE-DOORS.

SPECIFICATION forming part of Letters Patent No. 338,507, dated March 23, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, JOHN E. GAITLEY, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Knobs or Handles for Stove-Doors, of which the following is a specification.

Thisinvention relates to im provements upon the knobs or handles for stove-doors for which Letters Patent No. 804,925 were issued to me September 9, 1884; and my present invention has for its object to provide a simple, cheap, and efficient knob or handle which can be conveniently attached to a door by a screw-nut.

To such end my invention consists in a knob or handle made of a single strand of wire coiled spirally at one end into a handle, and having its other end bent and extended centrally through the coil in the form of a straight rod, the extremity of such rod, which projects from or beyond the inner end of the coil, being furnished with an external screw-thread for receiving a nut by which the inner coiled end of the handle can be clamped to the outside of the door when the threaded extension is passed therethrough and a nut is applied to such extension.

In the accompanying drawing, the figure represents a side elevation of a stove-door knob or handle constructed in accordance with my invention, and showing part of a stovedoor in dotted lines.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawing, where the number 1 indicates the knob or handle made from a single strand or strip of wire. This wire is at one end coiled spi rally to form the handle proper, the inner extremity, 2, of the coil being pressed upon the adjacent coil to produce an approximately flat bearing to seat upon the stove-door. The other end of the wire strand is bent laterally to form the bend 3, and the wire is thence turned and extended centrally through the coil in a straight line. The bend 3 forms the outer head of the knob or handle, and the straight part of the wire is extended from and beyond the inner end of the coil, to provide a shank which is screw'threaded interiorly, as shown at 4. This shank is designed to pass through an orifice formed in a stove-door, and to receive a screw-nut, 5, in such manner that the door will be between the inner bearing of the coil and the nut, whereby the handle can be firmly and substantially clamped in position to the door to serve as a means for manipulating the latter. In this construction the knob or handle is open and is not in contact with the central shank, so that there is but little cond ucting-surface for the heat, while the free circulation of air is permitted into and through the knob, whereby the parts are kept comparatively cool. The coil constitutes a spring, and by tightening up the nut the coil can be slightly compressed to regulate its tension, thus enabling the device to be always held tight and avoid rattling.

If desired, the knob may be provided with two nutsone on the inside of the stove-door and one on the outside, between the door and the inner extremity, 2, of the coilt-hus giving additional stiffness to the parts. Ordinarily, however, one nut arranged as shown will be sufficient to secure the knob.

Having thus described my invention, what I claim is- Aknob or handle consisting ofasingle strand of wire coiled spirally at one end, and at the opposite end bent and extended centrally through the coil, and having its extremity projecting from and beyond the inner end of the coil, and constructed with a screw-thread for receiving a nut or nuts to clamp the inner end of the coil to a stove-door, substantially as described.

In testimony whereof I aflix my signaturein presence of two witnesses.

JOHN E. GAITLEY.
